SCALE FACTOR
SCALE
FACTOR: 360<
Number of increments each revolution is divided into
Note: The PS-6400 keypad may time out if there are a large number of pulses
when changing scale factor. Do not cycle power during this operation, or data
may be lost.
Description
This function controls the number of increments into which one resolver revolution is
divided. A scale factor of 360 (0 to 359) allows the controller to operate in degrees. A
higher scale factor allows positions to be programmed more accurately. In some appli-
cations the scale factor can be set so each increment equals a unit of linear travel.
When the scale factor is changed, all programmed setpoints are recalculated to convert
them to the new scale factor. The keypad/display will be inoperative until the calcula-
tions are done.
Note: Speed compensation requires time to respond to accelerations, and longer
scale factors increase that response time.
